Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an appliance mounting device, and more particularly, to an apparatus for suspending and supporting appliances such as a chandelier from a ceiling or the like.

[Technical background of the invention]

Traditionally, when attaching heavy equipment to the ceiling, etc., the tightening force of wood screws was insufficient, so
An instrument mount having a structure as described in Japanese Patent No. 5363 is known. This equipment attachment is made by screwing a bolt onto a rotating support that is rotatably attached to a long and narrow hook, and inserting the hook into a vertical position attached to the bolt. The hooks are fixed to the top of the veranda, and the fixtures are suspended and supported from bolts hanging from the ceiling. However, with this structure, when the hook is horizontally locked, the upper end of the bolt protrudes from the bolt insertion part formed on the hook, so when the hook is attached to the bolt, the bolt cannot be inserted. If the hook extends above the upper end of the section, the hook hits the bolt and cannot be rotated in the horizontal direction, making it impossible to hang the hook on the ceiling.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and the upper end of the bolt is not located above the position of the bolt insertion part of the hook attached to the bolt when it is screwed into the rotation support attached to the hook. To provide a fixture mounting device which prevents the inconvenience of a hook not rotating in the horizontal direction when the hook is attached to a bolt and inserted into a hole in a construction surface such as a ceiling. It is something.

[Summary of the invention]

The present invention includes an elongated hook having a bolt insertion portion formed therein, a bolt, and a rotating support rotatably attached to the hook and having a threaded groove into which the bolt is screwed. In a device in which a hanging device is rotated vertically, attached to a bolt, inserted into a hole made in a construction surface such as a ceiling, and is locked by rotating the hanging device in a horizontal direction orthogonal to the bolt, the above-mentioned At the end of the bolt insertion part of the hook when the hook is attached to the bolt, so that the bolt does not exceed the position of the bolt insertion part of the hook when the hook is attached to the bolt. A regulating part is formed to abut the upper end of the bolt, so that the bolt does not prevent the hook from rotating horizontally from the state where it is attached to the bolt by vertically rotating it. .

[Embodiments of the invention]

The configuration of an embodiment of the present invention will be explained with reference to the drawings.

1 is a hook, which is formed in a roughly inverted U-shape in cross section;
The lower edges of both sides 2 and 3 have uneven locking edges _2a ,
It is formed in 3 _a .

Further, in the center of the upper surface of the hook 1, a long hole-shaped bolt insertion portion 4 is formed so as to be offset from the longitudinal center of the hook 1 toward one end.

Further, on the other end side of the bolt insertion part 4 of this hook 1, a regulating part 5 is formed by a protrusion cut inwardly.

Furthermore, an engaging portion 6 is cut and raised at one end of the upper surface of the hook 1 and projects inward.

Further, 7 is a rotation support, which is formed in a substantially annular shape.
A thread groove 9 into which a bolt 8 is screwed is formed on the inner peripheral surface. The rotation support 7 is connected to the hook 1.
A pivot pin is provided at one end side position of the bolt insertion part 4, which is offset to one end side of the bolt insertion part 4, which is offset to one end side from the longitudinal center of the hook 1 between both sides 2 and 3. It is rotatably attached at 10.

The bolt 8 is attached to the thread groove 9 of the rotation support 7.
is screwed into the

Next, the operation of this embodiment will be explained.

As shown in FIG. 3, when the bolt 8 is screwed onto the rotating support 7, the tip of the bolt 8 comes into contact with the regulating portion 5 of the hook 1, and the screwing position of the bolt 8 is regulated.

Then, as shown in FIG. 3, when the hook 1 is tilted vertically and attached to the bolt 8, the engaging portion 6 comes into contact with the bolt 8, and the hook 1 is easily rotated in the horizontal direction. In this state, when the hook 1 is inserted into a hole 12 formed in a construction surface, for example, the ceiling 11, and the lower end of the hook 1 comes out of the ceiling hole 12, the hook 1 will be tilted relative to the bolt 8. Since the center of gravity is attached, the center of gravity is in an unstable position, and when the hook 1 is rotated horizontally and the bolt 8 is pulled downward, the locking edges 2 _a and 3 _a at both ends of the hook 1 are rotated horizontally. is secured to the upper surface of the field edge 13. At this time, since the upper end of the bolt 8 is regulated by the regulating part 5 at the position of the bolt insertion part 4 of the hook 1, it is projected upward from the bolt insertion part 4 by horizontal rotation of the hook 1. ing. In this state, when the bolt 8 is rotated to adjust the length of the bolt 8 protruding downward from the ceiling 11,
The bolt 8 is moved upward by the screwing of the rotation support 7. After adjusting the protruding length of the bolt 8, the bolt 8
It is fastened with a nut 15 that is tightened and screwed into.

In the above embodiment, the bolt insertion portion 4 of the hook 1 is formed in the shape of a long hole on the upper surface, but the bolt insertion portion may be a recess formed by curving one side surface 2 toward the other side surface 3.

If the relationship between the bolt 8 and the hook 1 is reversed and the bolt 8 is screwed into the rotation support 7 as shown in FIG. 4, the end will be longer than the position where the rotation support 7 is pivotally supported. Since the end side is located downward, the center of gravity is located below the shaft support of the rotation support 7, and the hook 1 cannot be rotated horizontally, but in this case, the bolt 8 hits the regulating part 5, and the hook Tool 1 and bolt 8
Since it will not be possible to attach it to the hook 1 and bolt 8.
You can realize that you have reversed the relationship.

〔Effect of the invention〕

According to the present invention, when the hook is attached to the bolt, the bolt is attached to the upper end of the bolt insertion portion of the hook so that the bolt is not attached beyond the position of the bolt insertion portion of the hook. Since we have formed a regulating part that makes contact with the top end, when the bolt is inserted into a hole in a construction surface such as a ceiling with a hook attached to it, the top end of the bolt will come into contact with the hook and rotate horizontally. The hook can be rotated and locked in the horizontal direction without being blocked, and the installation operation is easy, and even if the relationship between the hook and the bolt is reversed, When the bolt hits the regulating part, the opposite relationship can be immediately recognized, there is no risk of erroneous operation, there is no need to increase the number of parts, and the product can be obtained at low cost.
